FIELD OF THE INVENTION

This invention relates to a warning apparatus providing an extendable ortelescoping strobe light to provide an easily viewed safety alert.

BACKGROUND OF THE INVENTION

Auto accident scenes pose hazards to oncoming traffic and are frequentlymarked with warning flares having limited burn time. Smaller mobilevehicles, such as wheelchairs and all terrain vehicles, are found intraffic, are not as visible in profile as other motor vehicles and maybe adorned with flashing warning lights.

Warning light devices are seen in U.S. Pat. No. 7,367,700 to Chasmar;U.S. Pat. No. 7,026,940 to Cherubini; U.S. Pat. No. 6,154,690 toColeman; U.S. Pat. No. 5,791,761 to Bryant et al; and U.S. Pat. No.6,035,567 to Cameron.

The patents referred to herein are provided herewith in an InformationDisclosure Statement in accordance with 37 CFR 1.97.

SUMMARY OF THE INVENTION

The Apparatus (1), presents a strobe light (11) via an telescoping lightmount (10). The telescoping light mount (10) is extended and retractedby an antenna drive motor (23) and alternatively manually. An insulatedelectrical conductor (28) is connected to a strobe or light socket (5)which is in electrical communication with the strobe light (11). Theinsulated electrical conductor (28) is wound on a negator reel (46)which is integral to negator spring reel assembly (32). A negator springhousing (420) contains a negator spring (400). When the telescopinglight mount (10) is extended manually or by the antenna drive motor(23), and thereby unwinds the insulated electrical conductor (28), thenegator spring (400) is spring biased exerting a retracting force on theinsulated electrical conductor (28). When the antenna drive motor (23)retracts the telescoping light mount (10) the spring biased negatorspring (400) returns to its relaxed position thereby reeling in andrewinding the insulated electrical conductor (28) on the negator reel(46).

DETAILED DESCRIPTION

FIGS. 1, 2 and 5 illustrates a telescoping strobe light assembly (1)shown contained in a case (14) with a case door (13). The case (14) anddoor (13) will generally be constructed of a rigid material includingmetals. The door (13) is hinged or otherwise connected to the case (14)by a means recognized by those of ordinary skills in case arts. It isrecognized, by those of ordinary skills in the mechanical and containerarts, that there will be many containers with various configurationsincluding different means of access and constructed of generally rigidmaterials including metals and plastics. The telescoping light mount(10) extends outwardly from the case (14). The telescoping light mount(10), most distal to the case (14), is fitted with a light socket (5) toreceive a warning light. The preferred embodiment is a socket (5) orconnector of a type which accommodates a strobe light (11). The socket(5) is in electrical communication with an insulated electricalconductor (28) which is extended or unwound from a reel provided by anegator spring reel assembly (32).

One embodiment of the assembly (1), seen in FIG. 5, contains a powersupply (45) comprised generally of a DC battery. This embodiment, with ahandle (56), is portable and may be used by officers at accident scenesin the place of flares. The assembly (1) will have an operating timeexceeding the burn time of a highway warning flare. In this embodimentthe telescoping light mount (10) will be manually extended andretracted. FIG. 1 shows an embodiment of the invention which willgenerally be affixed to a vehicle via a case bracket (15). The casebracket (15) is understood by those of ordinary skills in bracket artsto have many variations. Also seen is a strobe circuit and power (51),understood to comprise the electronic circuit required to produce anelectronic output as required for the operation of a strobe light (11).Seen is an electrical switch (58) between the power supply (45) and thestrobe circuit and power (51).

FIGS. 3, 4 and 5A illustrate the negator spring reel assembly (32) andbrush assembly (43). The negator spring reel assembly (32) is comprisedof a negator spring housing (420) which is integral with a negator reelassembly (38) by the interconnection via a hollow negator reel (46) andis composed, in the preferred embodiment, of rigid materials includingmetals and plastics.

The negator spring housing (420) encloses a cavity which is sized toreceive a coil spring (40). The negator spring housing (420) is closedor capped, distal to the negator reel assembly (38), by a generallyplanar negator spring reel housing cap (36) which is fastened by screwor bolt means (34) to the negator spring housing (420) via threadedapertures. The negator spring reel housing cap (36) has a centrallypositioned negator axle aperture (351) which is sized and shaped toreceive an elongated and cylindrically shaped negator axle (350). Thenegator axle (350) extends from the negator spring reel housing cap (36)negator axle aperture (351) through a hollow negator reel (46) and intoor proximal to a brush housing aperture (60) where the negator axle(350) is secured from rotation by screw or bolt means (34) through abrush housing aperture (60) and into a screw/bolt aperture in thenegator axle (350). It is seen that the negator axle (350) remainsstationary relative to the rotation of the negator reel assembly (38)and the negator spring housing (420).

The negator axle (350) is secured from rotation relative to the negatorreel assembly (38) by screw or bolt means (34) through a brush housingaperture (60) and into a screw/bolt aperture in the negator axle (350).The negator axle (350) is secured from rotation relative to the negatorspring housing (420) and negator spring reel housing cap (36) by screwor bolt means (34) through a bearing means (39) and through the negatoraxle aperture (351) and into a screw/bolt aperture in the negator axle(350). The bearing means (39), illustrated in FIG. 3, may be provided bya washer.

The negator reel assembly (38) has, most distal to the negator springreel housing cap (36), a conducting plate (66) comprising an electricalconducting material generally copper. Those of ordinary skills in theelectrical conducting arts will recognize that other materials willprovide an equivalent conduction characteristic. The conducting plate(66) is generally planar, is rotationally secured to the negator reelassembly (38) and may be inset in the negator reel assembly (38). Theconducting plate (66) is immediately proximal to a brush assemblyinsulated housing (52).

The negator reel (46) is generally cylindrical and interconnects thenegator spring housing (420) and the negator reel assembly (38). Thenegator spring housing (420), the negator reel (46) and the negator reelassembly (38) will generally be formed from metal or plastic as anintegral unit. An insulated electrical conductor (28) is wound aroundthe negator reel (46). The insulated electrical conductor (28) is inelectrical communication between the light socket (5) and the conductingplate (38). The insulated electrical conductor (28) is affixed byconductor affixing means (29) to the conducting plate (66) by screw,bolt/nut, solder or welding means as shown in FIG. 4.

The negator spring (400) has a negator spring inside end (405) and anegator spring outside end (410), as seen in FIG. 3 and is, in thepreferred embodiment a coil spring. The negator spring inside end (405)is centrally positioned within the negator spring housing (420). Thenegator axle (350) has a negator axle slot (352), centrally andlongitudinally positioned from the negator axle distal end (355) at orproximal to the negator spring reel housing cap (36), into which isreceived the negator spring inside end (405). The negator spring housing(420) has a negator spring housing inside wall slot (440) into which isreceived the negator spring outside end (410). The negator spring (400)is biased into tension or compression as the negator reel assembly (38)rotates to release the insulated electrical conductor (28) when thetelescoping light mount (10) is extended. The biased negator spring(400) reverses the rotation of the negator spring reel assembly (32)when the telescoping light mount (10) is retracted thus rewinding theinsulated electrical conductor (28) about the negator reel (46).

FIGS. 1, 2 and 5 illustrate the telescoping light mount (10) which maybe extended and retracted manually or by operation of a antennal drivemotor (23) which, for extension forces outwardly an antenna drive wire(24). Those of ordinary skills in antenna drive motors (23) willrecognize a variety of such drive motors which urge a stiff wire orcable, which is affixed distally to a telescoping light mount (10), toeither extend or retract the telescoping light mount (10). In thepreferred embodiment a conductor conduit (26) is positioned between thenegator spring reel assembly (32) and the telescoping light mount (10)at a location proximal the interconnection of the telescoping lightmount (10) and the case (14). The insulated electrical conductor (28)passes through the conductor conduit (26) and is thus shielded from wearfrom contact with the antenna drive wire (24). The conductor conduit(26) is affixed by conduit affixing means including wire ties, clampsand other such means known to those of ordinary skill in the conduitaffixing arts.

The negator spring reel assembly (32) is cylindrical in the preferredembodiment. The negator reel (46) separates the negator spring housing(420) and the negator reel assembly (38) by a space identified here asthe negator reel gap (44) as seen in FIGS. 2 and 4.

Seen in FIGS. 2, 3 and 4 is a brush assembly (43) which provideselectrical communication between an internal power supply (45) or powerfrom an external source via a power cable (46) connected, for example,to a vehicle battery and the strobe light (11). The brush assembly (43)is comprised of at least one brush assembly carbon (56), at least onebrush assembly spring (47), at least one brush assembly pin (48) movablypositioned in the at least one brush assembly insulated housing (52)within at least one brush assembly insulated housing apertures (60) inelectrical with the at least one brush assembly connector (49). The atleast one brush assembly pin (48) is elongated terminating in asubstantially planar end which exerts force on the at least one brushassembly spring (47) which in turn exerts force on the at least onebrush assembly carbon (56) which is urged into electrical contact withthe rotatable conducting plate (66). In the preferred embodiment thereare at least two brush assembly carbons (56). The at least one brushassembly connector (49) is connected by cable connecting means to astrobe power cable (53) which provides strobe power from a strobecircuit and power (51). The at least one brush assembly carbon (56) isunderstood by those of ordinary skills in the electrical brush assemblyarts to be composed primarily of carbon.

While a preferred embodiment of the present invention has been shown anddescribed, it will be apparent to those skilled in the art that manychanges and modifications may be made without departing from theinvention in its broader aspects. The appended claims are thereforeintended to cover all such changes and modifications as fall within thetrue spirit and scope of the invention.
